Fifth graders investigate how a pond ecosystem can change into a prairie or grassland ecosystem. They observe a small pond ecosystem in a two liter soda bottle, and examine and record changes over a two-week period of time on a worksheet.

Fourth graders investigate what natural events cause rocks to break apart and differentiate between erosion and weathering. They conduct an experiment with plaster of paris to observe why some rocks are hard and others break, and...

Students observe and analyze weathering. In this earth science lesson, students demonstrate physical and chemical weathering in two experiments, then write questions for a class Jeopardy game.

Students explore the value of insects in the natural world. For this insect lesson, students examine species of insects, collect and record data, and analyze the data.

In this solar storms worksheet, students read about the correlation between different astronomical events to find patters and new 'laws' of nature. Students use given statistical information about solar flares and coronal mass ejections...

Students make observations of ice as it melts. In this phase change lesson, students observe ice as it melts in a cup. They discuss their observations and place the cup of water into a freezer to change it back into ice.

Fourth graders experiment to see which objects decompose. In this compost lesson, 4th graders observe the changes of labeled objects in a bag. Leave the objects for one month and record the changes by observation and weight. Students...

Learn how to investigate the change in a graph by dragging the cursor to observe the change in the function. They use the TI calculator to graph their parabola.

Students explore the process of decomposition. In this science lesson, students carve a pumpkin and observe as it decomposes. Students compare the changes to an uncarved pumpkin. Students write about the disappearing pumpkin.

Students explore the diet of insects. In this "insects" biology instructional activity, students take a nature walk and collect various natural materials they think may be eaten by insects. Students sort and classify these materials into...

Fifth graders investigate how clouds and fog are made of tiny droplets of water. They discuss how clouds and fog are formed, then conduct an experiment in which they observe what happens when an ice cube is placed on top of a bottle...

Learners observe the effects of pollution on living organisms. In this pollution lesson plan, students observe fresh water Hydra and look at their structures and movement. They place samples of pond and lake water on the Hydra and...

Learners investigate the properties of water. For this chemistry of water lesson plan, students observe a demonstration of the properties of water using sand, sugar, oil, vinegar and salad dressing. Learners experiment with water,...

Students record scientific observations in a science journal.  In this season lesson, students make observations about each of the seasons and record in their journals.  Students record organisms response to seasonal changes...

Students observe offspring (mealworms) that do not initially resemble their parent organism (darkling beetles) throughout complete metamorphosis. They also create and maintain an appropriate habitat for the mealworms.

Student observe and quantify the respiration that occurs in yeast-molasses cultures. They complete an effective experiment in order to examine how to think critically about the results.

Students explore the parts of flowers and how they reproduce. They dissect flowers and observe the reproductive organs. Students observe anthers and ovaries of Tiger Lilies under a microscope. They investigate how insects and other...

Students use field research and traditional research to identify migrating species of birds as well as their migratory patterns. Students generate a list of questions regarding migration and a plan to research the questions. A field...

Young scholars observe crystals and their shapes and formation. In this crystal formation lesson, the teacher prepares crystal gardens for the students to observe, then the class finds examples of crystals in nature and observe a teacher...

Fourth graders investigate the role of environment in the life of three Native American tribes.  In this Native Americans lesson plan, 4th graders define environment, regions, and natural resources.  Students recognize how...

Students explore the water cycle. In this earth science lesson plan, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...

Learners investigate how rocks are modified into construction materials. In this building up and breaking down lesson plan, students explore what happens to building materials over time and how people modify natural materials. Learners...

First graders observe the effects of varying amounts of water, sun, and air on lima bean plants. They also predict and describe their outcomes in a written report.
